ASP.NET Core 8 LTS Hosting: Production Guide

.NET 8 LTS launched in November 2023 and is the most-deployed .NET version in production today. With mainstream support through November 2026, it remains the right baseline for teams shipping in 2025–2026 who want a stable target, mature library ecosystem, and well-understood operational characteristics — without committing to .NET 10's newer features.

This guide covers .NET 8 LTS in depth: what it ships, when to choose it over .NET 10, what hosting it correctly requires, and exactly what's included on every Adaptive ASP.NET Core 8 hosting plan.

Why .NET 8 LTS Still Matters in 2026

.NET 10 LTS is the newer LTS, but .NET 8 LTS isn't obsolete — it's the production-tested standard most teams are still on. Three reasons:

| Reason | Detail |

|---|---|

| Maturity | Two years of patches, well-understood edge cases, mature NuGet packages |

| Active support | Mainstream support through November 2026 (~18 more months from mid-2026) |

| Migration path | Code written for .NET 8 ports to .NET 10 with minimal changes (mostly target-framework bump) |

| Library compatibility | Every meaningful library has a working .NET 8 build (some .NET 10 builds are still in preview) |

| Team familiarity | Most teams have shipped .NET 8 apps; .NET 10 features take time to learn |

> 💡 The pragmatic rule: Pick .NET 10 LTS for greenfield projects starting today (longer support window). Pick .NET 8 LTS for in-flight projects you want to ship without taking on framework-version risk. Both run on the same Adaptive hosting plans.

What .NET 8 LTS Shipped

.NET 8 was a big release. The features that actually matter in production:

Native AOT for ASP.NET Core

• 30–50% smaller deploy footprint
• Sub-50 ms cold starts (vs 200–500 ms for JIT)
• Lower memory ceiling (no JIT compiler resident)
• Trimmed runtime — only what your code actually uses

Trade-off: not every library is AOT-compatible. Reflection-heavy libraries (older serializers, ORMs without source generators) may not work. EF Core 8 added partial AOT support; EF Core 9 and 10 improved it.

Improved Minimal APIs

Route grouping with MapGroup, better parameter binding, native form-data support, OpenAPI generation built into the framework:

var app = WebApplication.CreateBuilder(args).Build();
var customers = app.MapGroup("/customers")
.RequireAuthorization()
.WithOpenApi();
customers.MapGet("/{id:int}", async (int id, AppDb db) =>
await db.Customers.FindAsync(id) is Customer c ? Results.Ok(c) : Results.NotFound());
customers.MapPost("/", async (Customer c, AppDb db) => {
db.Customers.Add(c);
await db.SaveChangesAsync();
return Results.Created($"/customers/{c.Id}", c);
});
app.Run();

Less ceremony than controllers. Easier to grep. Perfect for microservice surfaces.

Identity API Endpoints

ASP.NET Core Identity got endpoint-based registration and login (MapIdentityApi), eliminating boilerplate for SPA scenarios:

builder.Services.AddIdentityApiEndpoints<IdentityUser>()
.AddEntityFrameworkStores<AppDb>();
app.MapIdentityApi<IdentityUser>();

Adds /register, /login, /refresh, /confirmEmail, /forgotPassword, /resetPassword endpoints automatically. Useful for Blazor WebAssembly + API backends.

Rate Limiting Middleware (Built-in)

Native rate limiting (added in .NET 7, matured in .NET 8):

builder.Services.AddRateLimiter(o =>
{
o.AddFixedWindowLimiter("login", opts =>
{
opts.PermitLimit = 5;
opts.Window = TimeSpan.FromMinutes(1);
});
});
app.UseRateLimiter();
app.MapPost("/login", LoginHandler).RequireRateLimiting("login");

Critical for any endpoint that touches auth, password reset, or expensive queries.

Performance Improvements

The .NET 8 runtime is measurably faster than .NET 6/7:

• Dynamic PGO improved (up to 20% throughput gain on hot paths)
• JIT inlining of more methods
• System.Text.Json ~2× faster on common operations
• Garbage collection reduced Gen-2 pauses 20–40%
• HTTP/2 Kestrel flow control improvements

On the same code, expect 10–25% throughput improvement vs .NET 6.

Blazor United (Preview in 8, GA in 9)

.NET 8 introduced the unified Blazor render-mode model: Server, WebAssembly, Auto, and Static SSR in the same project. The model went GA in .NET 9 and .NET 10 — see our Blazor hosting guide for the full breakdown.

When to Choose .NET 8 LTS Over .NET 10 LTS

| Scenario | Recommendation |

|---|---|

| Greenfield project starting in mid-2026, shipping in 6+ months | .NET 10 LTS (longer support window, AI features, faster runtime) |

| Project in development now, shipping in next 1–3 months | .NET 8 LTS (mature ecosystem, no late-binding library risk) |

| Existing .NET 6 / 7 application | .NET 8 LTS first, then .NET 10 LTS when team is ready |

| Application requires libraries without .NET 10 builds yet | .NET 8 LTS (every library has stable .NET 8 builds) |

| Application uses heavy AOT compilation | .NET 10 LTS (better AOT story) |

| Team uses AI features (Microsoft.Extensions.AI) | .NET 10 LTS (built-in) |

| Application needs post-quantum cryptography | .NET 10 LTS (ML-KEM, ML-DSA) |

| Cost-optimized app, performance not critical | Either — pick on team preference |

What .NET 8 Hosting Should Look Like

Modern runtime features only land in production when the hosting layer cooperates. Specifically for .NET 8:

Windows Server 2022 + IIS 10 with ANCM v2

ASP.NET Core 8 deploys to IIS via the ASP.NET Core Module v2 (ANCM). On Adaptive's plans, this is preinstalled on Windows Server 2022 + IIS 10 — no manual configuration. Your web.config is auto-generated by dotnet publish:

<configuration>
<location path="." inheritInChildApplications="false">
<system.webServer>
<handlers>
<add name="aspNetCore" path="" verb="" modules="AspNetCoreModuleV2" resourceType="Unspecified" />
</handlers>
<aspNetCore processPath=".\YourApp.exe" hostingModel="inprocess" />
</system.webServer>
</location>
</configuration>

Dedicated IIS Application Pools

Every Adaptive plan ships with dedicated IIS Application Pools per site:

| Plan | App Pool RAM | Websites |

|---|---|---|

| Developer | 1 GB | 2 |

| Business | 2 GB | 5 |

| Professional | 4 GB | 10 |

Higher tiers add Higher Priority Resource Scheduling (Business and Professional) and Higher Priority CPU Scheduling (Professional).

Real SQL Server 2022 (Not Express)

If your hosting provider includes "SQL Server" but it's actually Express, you're capped before the .NET 8 runtime even matters. SQL Server Express limits:

• 10 GB max database size
• 1.4 GB memory cap
• Single-CPU bottleneck
• No Query Store, no ledger tables, limited Always Encrypted
• No SQL Agent for scheduled jobs

Every Adaptive plan includes full SQL Server 2022 databases (2 / 5 / 10 by plan), not Express. Plus MariaDB databases alongside for PHP-compatible workloads (2 / 5 / 10 by plan).

Health Checks and Auto-Restart

ASP.NET Core 8's health-check middleware is well-supported. A /health endpoint exercising your critical dependencies:

builder.Services.AddHealthChecks()
.AddSqlServer(builder.Configuration.GetConnectionString("Default")!)
.AddCheck<DiskSpaceHealthCheck>("disk-space");
app.MapHealthChecks("/health");

IIS on Adaptive is configured to restart pools that fail their health probe — your app self-heals if a transient DB issue or memory leak triggers an unhealthy state.

.NET 8 → .NET 10 Migration Path

When you're ready to move from .NET 8 to .NET 10 LTS, the migration is usually a single afternoon for most apps:

• Update ` in your .csproj to net10.0
• Update NuGet packages: dotnet outdated -u or dotnet list package --outdated, then upgrade
• Review middleware order changes — minor defaults shifted between 8 and 10
• Test SignalR clients — protocol bumps may require client updates
• Re-publish with the .NET 10 SDK

Yes. true` works for most ASP.NET Core 8 apps. EF Core 8 has partial AOT support; if you use reflection-heavy libraries, validate AOT compatibility in a side branch first. .NET 9 and .NET 10 improved AOT coverage further.

What's the cold-start cost for a .NET 8 ASP.NET Core app?

On Adaptive's IIS 10 with dedicated app pools: 80–150 ms typical for a small API on first request after pool start. With Native AOT enabled: 30–60 ms. App pool recycling happens on your schedule (or never), so cold starts only occur on initial deployment.

Does .NET 8 work with SQL Server 2022 features like ledger tables?

Yes, fully. EF Core 8 has first-class support for SQL Server 2022 features including ledger tables, JSON columns, and Always Encrypted with enclaves. (EF Core 10 added vector search; the rest is in EF Core 8 and later.)

What's the difference between .NET 8 LTS and .NET 9 (non-LTS)?

.NET 9 is a Standard Term Support release — supported only for 18 months (until May 2026). It shipped between LTS versions (.NET 8 → .NET 10). For production workloads, prefer LTS versions: .NET 8 LTS (until Nov 2026) or .NET 10 LTS (until Nov 2028). See our .NET Core 9 hosting deep-dive for details on the in-between release.
